The Disease Triangle: A plant pathological paradigm revisited
2001年1月1日 · The disease triangle (Figure 1) is one of the first concepts encountered by college students in an introductory plant pathology course (1) and often may be re-encountered in higher level classes as a fundamental principle of the factors involved in disease causation. Thus, the figure illustrates one of the paradigms in plant pathology; that is ...
The Disease Triangle: Fundamental Concept for Disease …
2018年11月28日 · Plant diseases– their occurrence and severity– result from the impact of three factors: the host plant, the pathogen, and the environmental conditions. This is represented with the disease triangle. If any one of the three factors is missing, the triangle is not complete, no disease will occur.
Re-Envisioning the Plant Disease Triangle: Full Integration of the …
The disease triangle is a structurally simple but conceptually rich model that is used in plant pathology and other fields of study to explain infectious disease as an outcome of the three-way relationship between a host, a pathogen, and their environment.
(PDF) Plant Disease Epidemiology: Disease Triangle and Forecasting ...
2018年2月1日 · It is the triangular relationship in which plant disease results only in the presence of a virulent pathogen, a susceptible host, and a disease-friendly conductive environment and their ...
Traditionally speaking the disease triangle is most often comprised of three factors: host, organism, environment. However, in some less traditional settings a fourth factor (time) is included in a four-dimensional figure to show the impact of time in addition to …
14.9 Plant disease basics: the disease triangle - David Moore
The disease triangle illustrating the phenomenon of plant disease as the interior space of a triangle with the three essential factors (susceptible host, favourable environment for disease, and pathogen) at the vertices.
Disease Triangle | College of Agricultural Sciences
If any one of the three is missing, plant disease does not occur. The factors are: A susceptible host; A virulent pathogen (one that can cause disease), and; A suitable environment; Plant pathologists refer to this as the disease triangle. You can manage elements of the disease triangle to control disease.
What is a disease? Any abnormal condition that damages a plant and reduces its productivity or usefulness to man. Two types of diseases. 1. Non-infectious (abiotic) » Not caused by a living parasitic organism; usually an environmental factor 2. Infectious (biotic) » Caused by a living parasitic organism
The disease triangle is a fundamental concept in plant pathology. Disease occurs only when all three sides of the triangle are present: a susceptible host, apathogen (the agent that causes disease), and an environment favorable for disease to develop. Plant diseases are managed by manipulating the disease triangle: the plant, the pathogen, and ...
The plant disease triangle facing climate change: a molecular ...
2024年8月1日 · Recent studies have identified climate-sensitive molecular pathways that can result in plants being more susceptible to infection under unfavorable conditions. Here, we review how expected changes in climate will impact plant–pathogen interactions, with a focus on mechanisms regulating plant immunity and microbial virulence strategies.
